Duration

A spell's duration entry tells you how long the magical energy of the spell lasts. Timed Durations Many durations are measured in rounds, minutes, hours, or other increments. When the time is up, the magic goes away and the spell ends. If a spell's duration is variable, the duration is rolled secretly so the caster doesn't know how long the spell will last. Instantaneous The spell energy comes and goes the instant the spell is cast, though the consequences might be long-lasting. Permanent The energy remains as long as the effect does. This means the spell is vulnerable to dispel magic. Subjects, Effects, and Areas If the spell affects creatures directly, the result travels with the subjects for the spell's duration. If the spell creates an effect, the effect lasts for the duration. The effect might move or remain still. Such an effect can be destroyed prior to when its duration ends. If the spell affects an area, then the spell stays with that area for its duration. Creatures become subject to the spell when they enter the area and are no longer subject to it when they leave. Touch Spells and Holding the Charge In most cases, if you don't discharge a touch spell on the round you cast it, you can hold the charge (postpone the discharge of the spell) indefinitely. You can make touch attacks round after round until the spell is discharged. If you cast another spell, the touch spell dissipates. Discharge Occasionally a spell lasts for a set duration, or until triggered or discharged.
